The Bothnian Bay area features numerous small island destinations equipped with recreational structures maintained by Metsähallitus, suitable for day trips. In addition to the islands within the Bothnian Bay National Park, there are islands with recreational structures situated between Oulu and Kemi, near the islands that are part of the Natura 2000 area of the Bothnian Bay islands.
The largest guest harbors along the coast between Oulu and Kemi are Marjaniemi on Hailuoto, the harbors of Hietasaari and Meritulli in Oulu, Vatunki in Kuivaniemi in Ii, and Uleninranta in Kemi. The services at these guest harbors are managed by municipalities, cities or entrepreneurs.
A coastal route runs parallel to the shoreline between Oulu and Kemi, with a minimum depth of 1.8 meters.
There is no regular public transport to the islands, but some can be accessed using transport services provided by entrepreneurs. However, having one’s own vessel is generally the best way to reach the islands during the summer. Some islands are popular skiing destinations in winter, but there are no marked ski trails leading to them.
During winter, those traveling on the sea ice should take into account the deep-water channel between Oulu and Kemi, which is kept open by an icebreaker. The deep-water channel also divides the marine areas of Bothnian Bay National Park into two parts, affecting the accessibility of the park’s islands by skiing or snowmobiling.

Pensaskari is not as popular a skiing destination as Vähä-Huituri and Selkä-Sarvi, the other islands in the national park, as there are no accommodation facilities. Those planning a day skiing trip to the island should take into account the Kemi-Tornio shipping channel, which passes through Sarvenselkä, west of Pensaskari. Due to the shipping lane, it is not possible to ski from Pensaskari to the outer islands of the national park, such as Selkä-Sarvi.
The distance from Letto in Tornio to Pensaskari is approximately 10 km. Alternatively, one can ski from Kemi (about 16 km) or Kemi Ajos (about 13 km). There is no marked ski trail to the island. If you are unfamiliar with moving on sea ice or the local current spots, travel with an experienced sea ice traveler.
